Laptop magazine has an annual rating of laptop quality metric, but they are somewhat biased towards those with the best reviews i.e. Apple.

A warranty vendor Squaretrade also has a report on laptop
replacement during a 3 year warranty.
Here is where "perceived" reliability was the metric. I'd probably wouldn't put much weight on the results of this one, fanboys probably jumped on this one hard to make sure their favorite computer was represented.
Personally I used to like IBM Thinkpads, when IBM still owned the brand and prior to it's complete buyout by Lenovo. Lenovo seems to have lost the original Thinkpad quality. HP well I would stay away from them, I have an HP Envy currently and it's not that well made, but has decent sound. That said their Elitebook line (which is very expensive for what you get) is quite nice, though the company I worked for had a lot of overheating and reliability problems with them, so they eventually switched to Dell.
FWIW, I'm currently using a DEL XPS for work (FPGA design and simulation) and it runs cool, has a decent keyboard (though I primarily use an external one in the office), a nice display, and crummy sound quality.
